HOUSEHOLD-LAMP.

Specification of Letters Patent.

Patented May 11, 1920.

Application filed September 4, 1919. Serial No. 321,683.

To all whom it may concern Be it known that I, HENRI GALoPIN, a subject of the King of Great Britain, residing at Temple Court Place, Melbourne, in the State of Victoria, Australia, instrument maker, have invented certain new and use: ful Improvements in Household-Lamps, of which the following is a specification.

This invention relates to kerosene lamps having circular wicks and used principally for household illumination and the object is to facilitate control of and access to the wick to insure maximum illumination and obviate smoking of the lamp.

For this purpose improved lamprwick control mechanism has been devised which, brieflystated, comprises a rotatable spring jaw within the oil reservoir adapted by a swinging movement to be sprung into engagement with the wick and while holding same firmly against the central tube said jaw and wick are capable of longitudinal adjustment on said tube. This adjustment is effected by means of vertical movement of an angular wire extending from the jaw and having a vertical stem portion projecting up through the oil reservoir where it is journaled to partially rotate in a bearing sleeve or socket thereon. The stem is provided at its upper end with a finger grip for adjustment of the wick, which grip projects normally through a slot in the bearing sleeve or said grip may be raised through the medium of the upward movement of the chimney carrier in which latter case a lateral projection carried by said carrier engages the underside of said finger grip.

The higher than usual 'to permit ready access to the wick is supported on a standard vertically slidable in a spring tongue guide which maintains the carrier in adjusted po-. sition.

The accompanying drawings illustrate the invention and therein Figure 1 is a central vertical section taken through portion of a lamp incorporating the improvements above enumerated.

Fig. 2 is a plan of the lamp with parts removed, and

Referring to these drawings it will be seen that the spring jaw 1 is approximately semicircular with its extremity 2 curved outwardly and its interior surface preferably formed with wick-gripping means such as knife edges 3 (Figs. 3 and 9). Said jaw is provided with a stout angular wire, the lower portion or arm 1 being approximately horizontal and connected to one side of the jawand the other portion or stem 5 is Vertical and projected up through a socket 6 on the top of the oil reservoir 7 and into a vertical bearing sleeve 8 screw threaded as at 9 to be fitted to said socket 6. The arm 4 of the jawis thus pivoted by means of the stem in the bearing sleeve, so that partial rotation of the pivoted stem 5 causes the jaw to swing to embrace the wick W as illustrated in F ig. 3.

The bearing sleeve 8 is formed with a vertical slot 10 extending down from its top edge, through which protrudes a finger grip 11, provided on the upper end of the stem 5.

Such finger grip being formed for instance.

by merely bending the upper end of the wire stem as illustrated. The height to which the stem may be raised is controlled by a regu1ating screw 12- formed with a milled head and screwed into the mouth of the bearing sleeve 8, the shank of said screw being split longitudinally so as to give it a-certain amount of spring, and thus facilitate engagement of the threads.

In order to spring the jaw 1 into engagement with the wick, the screw 12 is removed and the stem 5, with its finger grip 11 raised out ofthe slot 10 in the bearing sleeve 8, is partially rotated in said sleeve as illustrated in Fig. 3 whereby the'jaw is turned in a horizontal plane and embraces the wick with a spring grip thus holding same firmly against the fixed central wick tube 13 111 the reservoir 7 of the lamp; subsequently the finger grip is dropped into the slot 10 which prevents rotation of the stem 5 and release of the jaw. The grip of the jaw is not so great as to prevent the wick being slid vertically up or down the tube 13 my manlpu lation of the finger grip but it is sufiieient to maintain the wick stationary and likewise the finger grip in adjusted position. Thus the finger grip 11 or upper end of the stem may be raised till it abuts against the bottom of the screw 12 when the wick will be raised to the height convenient for lighting or trimming. It will be evident that by reversing the rotation of the stem 5 as above stated, the spring jaw is released from the wick and may be removed from the reservoir through the socket 6 subsequent to the bearing sleeve 8 being unscrewed from its socket 6.

The finger grip 11 may be raised through the medium of the upward movement of the chimney carrier 14. As illustrated in Figs. 1, 2 and 8 the means consists of an arm 15 projecting down from alug 19 on the ring shaped carrier 14 and formed at its lower end with a lateral foot 16 taking under the finger grip 11. This arm 15 is preferably attached to the lug 19 of the carrier by a pivot 17 and bears at one side against a shoulder 18 formed on said lug by means of which construction the arm may be swung to one side to free the foot 16 from the finger grip 11.

To the lug 19 of the chimney carrier is fixed by means of a nut 20 a vertical stand ard 21 non-circular in cross section and preferably rectangular which slidably fits a correspondingly shaped metal socket 22 projecting above the top of the reservoir 7 and extending down into same and closed at the bottom. The upper end of the socket is formed with vertical splits 23 and the tongues 24 formed thereby act as springs to grip the standard in the socket 22.

Means are provided to limit the upward movement of the standard and consequently the chimney carrier and for this purpose one side of the standard is provided with a vertical groove 25 adapted to receive a bevel catch 26,- projecting through an aperture 27 formed in the socket 22 and fixed to a spring 28 attached to the outside of said socket.

The groove 25 i'sclosed at the bottom to form a stop 29 which abuts against the catch 26 when the standard is raised toits maximum height in the socket 22 but by lifting the spring 28, which has a bent end 30 for this purpose, the catch is freed from the stop, when the standard may be lifted out of the socket.
